MUSIC-PLAYER VALVE-ACTION.

Specification of Letters Patent.

Patented July 30, 1918.

To all whom it may concern:

Be it known that I, ROBERT A. GALLY, a citizen of the United States, and residing at Cincinnati in the county-of Hamilton and State of hio, have invented certain new and useful Improvements in Music-Player pneumatic 1, thus holding the pneumatic 1 irto the chest 5 but allowing its easy removal Valve-Actions, of which the following is a specification.

In this 'applicants prior Patent #1,101,- i

919, June 30, 1914, is set forth and claimed a plurality of controlling pneumatics and valves to a single power pneumatic, and the moving board of the power pneumatic adapted to return the stroke valve'to its seat. That patent also mentions, page 8, lines 101 to 104, that the two primary valves can be operated by a single oblong pnuematic arranged to be free to rise at one end in ad Vance of the other. In the present invention two valves are disposed at two distant points of a lever, and a single pneumaticis disposed in operative position to the said lever but intermediate the two said valves, thus enabling successive action of the'two valves from the one pneumatic, and a peculiar primary pneumatic is provided so disposed as to return the one or both valves, either from the air of the power pneumatic when the same is opened to the return normal atmospheric pressure air servlce, or to 1 act of a power pneumatic and the novel valve and primary pneumatic arrangement with an intermittent return pneumatic, and Fig. 2 is a similar view of a modified structure with the return pneumatic adapted to constant action.

A striker pneumatic 1 has a moving board 2 and a fixed board 3, the fixed board 3 removably attached to the valve board 4 of the action chest 5. Such attachment'is conveniently made by means of a clip or plate 6 fastened to the valve board 4 and having a hole in the upper end of the said clip 6 in which hole a pin 7 is engaged when the pneumatic 1 isin position, the" pin 7 being fast with the heel part of the pneumatic 1. At the front of the chest 5 the valve board 4 is extended farther front than the pouch board 8 of the chest 5, and a screw 9 is passed through the front part of the valve board 4 and 'into the fixed board 3 of the when desired.

In the fixed board 3 of the pneumatic 1 is a recess 10 in which the valves 11 and 12 are positioned, somewhat similar to the structure of said prior Patent #1,101,919. The valve 11 controls the connection of the pneumatic 1 to the air chest 5, which chest 5 is understood to be connected to any suitable air suction means, the said valve being normally closed. The valve 12 controls the connection of the pneumatic 1 to the outer air through the channel 13 in the fixed heel' part of the pneumatic 1, said valve 12 being normally away from the seat at the inner end of channel 13. These two valves'll, 12, each have anactuating rod 14, 15, the

lower end of each said rods being loosely engaged in a hole in a lever 16, one rod near each end of the said lever. Intermediate the two rods 14, 15, a follower button 17 engages the said lever 16 by a rocking joint 18, and a pouch 19 or other suitable pneumaticis positioned to. act on the said part of the lever 16 intermediate the two valve rods 14, 15. A duct 20 has the usual tube 21 connecting said duct 20 fromthe pneumatic socket 22 which controls the action of the pouch 19 and follower button 17, a usual bleed return vent 23 serving to allow the return of the pouch 19 and follower 17 at the end of anoperation of the valves 11, 12 and the pneumatic 1.

When air. is admitted through the tube 21 and duct 20 from any control aperture of a tracker bar, manual valve, or other venting means, the pneumatic socket 22 and its pouch 19 are inflated, thus raising the lever 16. As the valve 11 has the suction load of its port 24, while the valve 12 has practically very little normal suction load, the port under the lower face being small, the valve 12 is lifted by its rod 15 raised by that end of the lever 16, the valve 11 holding down its rod 14 and that end of the lever 16, that end of the lever 16 then being 1 the fulcrum for its movement by thefollower 17,- which follower 17 and pouch 19 pneumatic. 1 is then collapsed by the suction v oat-air from the chest 5, and as its moving boardp2 is drawn down it starts the action -o11=thcrspning26 which is of less dimension than the expanded distance between the moving board 2 anc'lqthe {opposite :part of the valve unit 11, as the felt cap 27 on which this spring is'mounted the moving board2 being brought into contact \with the spring 26,thus preparing'for a prompt revturnof the valve 511 when its return move- :ment is started by the collapse of the pouch -19. -As the moving board 2 continues its closing movement it increases the compression ofthe spring 26. The spring 26 may be mounted on the valve unit as shown, or 0n the moving board 2 as shown in applicanfis aforementioned prior Patent ,-.-/;51,'1-0l, 919,, although the present mounting onthe cap 27 of the valve 11 makes convenient the :removal of the spring :at any time.

A- check 28 is carried :by the moving board 2 in similar manner to that shown in said prior Patent 1,101,919., although the present structure is improved by-havin g the said check '28 engage vthe cap 27 which rests on valve 11, instead of having that check en- ,gage the valve rod :14- as in the said prior patent, the present structure insuring againsta ny tendency .to slide the rod 14 .down in the valve 11. This check 28 has means for regulation by a screw extending tothe outer face of the moving board 2, as in the prior Patent #1,101,919, and it is thus possible to regulate this check 28 so that it will return the valve 11 almost to its seat as the moving board 2 reaches the desired limit of stroke, and at the same time prepares the valve 11 2501 a very slight motion to reach its seat over. port 24 as the V pouch 19is allowed to collapse at the finish of an operation of the device.

A return pouch29 is placed on the inner face or? the valve. board 4, its interior being connected to the-interior of the striker pneumatic2 around the rod 115 when the valve '12 is raised at all. i

At the normal inactive position and condition of-th-e valves 11 andl2, as shown in Fig. 1, the interior of the striker pneumatic l-is open to the normal atmospheric pressure outer air, and-the-valve '12 is seated b'ver the air duct surrounding the rod 15, thu's closing the interior of the return pouch 29 from the outer air of the interior of the striker pneumatic 1. "When the tube 21 and duct 20' h'a've been vented to the outer air and the valve 12 starts its rise, the outer air of the interior of the striker pneumatic 1 is connected to the interior of the return ,pouch 29, and 'that'pouch pulls slightly againstthe rise oi the valve 12, but as there is no suction or other load on the valve 12 during its rising movement, that pull of :the' return pouch .29 is no .d'etri1nent,.and when the valve 12 reaches the seat 25 and the valve 11 starts to rise and connects the suction of the chest 5 to the interior of the striker pneumatic 1, that same suction is also instantly connected 110'11116311'1139-1101 of the return pouch 29, said return pouch 29 thus ibeingxrem derediinactive at the sameinstant that the suction commences to ,pull down on the valve 12,:and :thus :the retunn pouch 29 has no action against the holding of :the valve 12 to the seat .25 by the pouch 19 at such time 1 and condition of !l3l16S6"el6I1'l(-}IltF-3.

When the :tube21 and duct 2( are againclosed :to the -outer air, and the return vent 23 allows the pouch 19 to be col zlapsed by the pull of the valves 11 and 112 through their rods 14: and 15 and lever16, the return action of these valves is as tollows: The valves 11 and start to return, and the valve 11 usually being held almost entirely closed to its seat over the port 24:, reaches a complete closure before the valve 12 has more "than just: started to leave the seat 25 of outer air channel-13, thus avoiding any air-cut noise of air passing the seat-25 clear'through .the port 24. Alt such moment of initial opening :of the valve f-romthe seat 25, the outeruair is instantly connected to the interior of thereturn pouch which return pouch then ic'ommences to pull down the rod 15 to aid the quick opening of the seat 25 and-"enter air channel 1 3. 7 As The valve "'12 reaches its-original normal position of rest on the valve board 4, the connection to the interior of the return pouch 29 is again closed, thus rendering the return pouch inactive so that the next initial upward motion of the valve 112 may be easily etliected by tliie pouch 19, and also" that (lll}" ing the normal condition of non-operation, no loss of air will be allowed to pass dow to and through the pores of the return pouch "29;

If no return pouch 29 were employed, the

return action of the valve 12 would not he as quick, ancliit would require closer set throw of less elliciency, such two conditions not allowing as rapid repetition as when the return pouch is employed; The ouiter air service channel placed in fined hee l' piece 30' which c i from the hinge 30f of the st1. .l :einae are attached a the fixed boards "01' the said pneumatic, the air channel 13 extending inwardly from the heel end of the pneumatic to the downwardly opening port leading to the rear part of the recess 10 of the upper face of the heel piece is slanted downwardly from the hinge end of the pneumatic 1 in toward themain part of the pneumatic 1, and the rear end of the moving board 2 is hinged to the high outer end of the heel piece 30.

Fig. 2 is a modification of the return pouch idea, the modified form having the return pouch 31 disposed intermediate of the two valve rods 14, 15, and thereby acting on the lever'16'to exert a return force against both the valves 11, 12. I As'shown in Fig. 2 the return pouch 31 is constantly connected to the outer air, so that it is always active, but unlike a mechanical spring applied to a pneumatic valve, the return pouch 31 has a power always of the same ratio to the valve loads and the main pouch 19 no matter what degree of air tension, and so does the return pouch 29 of Fig. 1.

The intermediatelypositioned pouch 31 has less power against the rise of each valve 11, 12, than the return pouch 29 acting directly onthe rod 15 of valve 12, therefore it is not necessary to make the return pouch 31 so small as the return pouch 29.

To prevent too great a movement of the valvell, acheck 32 is employed at or near the end of the lever 16 adjacent the rod 14:

.of the said valve 11.
